Does MRI cause device dysfunction in patients with an active implantable cardioverter defibrillator?
MRI in patients with an active ICD can cause severe device dysfunction, including inappropriate shock triggers and altered pacing thresholds, reinforcing that it remains contraindicated.
Answers are grounded in this paper and cite their sources.
MRI may induce ICD dysfunction including VF detection and threshold rise; leaves open need for prospective safety data.
